All printers showing offline

This morning about an hour ago, I set off 8 print jobs to various machines in my fleet. Those are all running, was getting ready to send another job to another printer, and it’s showing every printer offline across 5 different raspberries. Hoping this is just a temp thing as it’s going to be 5 hrs before I can reboot printers. The PC has been rebooted, no change.

problem seemed to resolve itself after a few hours
